Abstract (en)

An object detection device may include: a converter configured to convert a transmission signal radiated towards an object into a digital transmission signal and a received signal reflected from the object into a digital received signal, according to a predetermined sampling period; and at least one processor configured to: interpolate between elements of the digital transmission signal and the digital received signal that have the predetermined sampling period, to obtain an interpolated transmission signal and an interpolated received signal; remove noise from each of the interpolated transmission signal and the interpolated received signal; generate a cross-correlation signal between the interpolated transmission signal from which the noise is removed and the interpolated received signal from which the noise is removed; and acquire a three-dimensional (3D) image of the object based on at least one peak value of the cross-correlation signal.
